SPECIFICATION forming part of Letters latent No. 764,332, dated July 5,1904.

Application filed April 8, 1904. Serial No. 202,194. (No model.)

To @LZ w/zolrt t may con/cern:

Be it known that I, RALPH BAGGALEY, oil` Pittsburg, in the countyot'Allegheny and State of Pennsylvania, have invented a new and usefulConverter,oiI which the following is a specification, reference beinghad to the accompanying drawings, in which- Figure lis a verticallongitudinal section of the converter. Fig. 2 is a verticalcross-section on the line Il II of Fig. l. Fig. 3 is a detail view on alarger scale.

.My invention provides means by'which a Bessemer converter used fortreating copper matte can be cooled with air and the extent of thecooling and the place of its application regulated as desired.

ln the drawings, 2 represents the exterior metal shell of a converter,having an interior brick lining 3, back of which is the air-coolingdevice which forms the subject of the present invention. A series ofhorizontal pipes 4 extend from end to end of the converter within theshell, and these pipes, oli' which l show three, are open at the ends,and they supply the air for the cooling-channels, which extendtransversely around the sides et the converter.` For that reason theyshould be made as large as convenient. They are covered with blocks 4,of brick, tile, or metal, having a series of lateral holes 5 5,communieating with holes in the pipes 4, adapted to receive the ends ofother metal pipes, 6, which 4 extend upward along the sides of theconverter and terminate at short tubes 7, open at the end outside theshell and having lateral holes bb, which register with the pipes. 1nlike manner at the ends of the converter are blocks il, extendingthrough the converter-shell intoV the lining and having lateral holes,into which are fitted pipes 6', which` extend up te tubes 7. The pipes 66 are embedded in hollow bricks, tiles, or metal blocks 8 8, which arestrung upon the pipes and are thus built into a compact structure on theinterior of the metal shell, and within this structure is the lining 3,preferably of magnesite brick. The invention thus affords within themetal converter-shell a large number of vertical airpassagescommunicating at the bottom with the external air through the horizontalpassages 4 4, and at the top through the tu bes 7,

so that there will be a natural circulation of air, which will cool thepipes and thus cool the converter-lining, to which the pipes present alarge area 0i contact. It it is desired to localize the cooling action,the tubes 7 7 at the places not needed to be cooled may be closed with'screw caps or plugs 9, which will at once stop the circulation of airtherethrough, or the circulation may be established in all the pipes orclosed in all ot' them. In like manner it may be found that acirculating air current through the outer pipes may be suilicient toaccomplish the result, and this can be effected by capping the two innerpipes 4 4 at each. end of the converter, which will have have the eiiectoi preventing any air-circulation through the entire series of pipesconnected therewith. The hotter the convertershell and lining become themore rapid will be the air-circulation and the more eilicient thecooling action. This is accomplished automatically and without theexpense and inconvenience of using water or `forced air. The degree ofthe cooling action over the entire area can be regulated at will andwithout expense by the three complete systems ot' pipes, and the coolingmay be localized at any portion of the shell or heads, as describedabove.

"he converter' may be provided with burn ers B, supplying flame from thejets of oil or gas above the bath.

The employment of the upright metal pipes on which the hollow bricks arestrung is im portant, because if they were not employed the air-passageswould become clogged in use or in the operation oi laying the blockswith mortar, clay, or cement. This will not occur with the metal pipes.

Within the scope of my invention as de- {ined in the claims the partsmay be modified, since What I claim is.

1. A converter having ventilated passages open to the air at the bottom,and other passages leading therefrom upward along the shell;substantially as described.

2. A converter having a series of ventilating air-passages open to theatmosphere above and below, the inlet being lower .than the outlet;substantially as described.

3. A converter having ventilated passages IOO IO stantially asdescribed.

5. A converter having' ventilated passages open to the air at thebottom, and other pas# sages leading therefrom along the shell, saidconverter having a burner for supplying auX- iliary heat within thesame; substantially as I5 described.

In testimony whereof I have hereunto set my hand.
